Colorado usually releases forms for the current tax year between January and April. We last updated Colorado Form 104PN from the Department of Revenue in January 2024.
Form 104PN is a Colorado Individual Income Tax form. Many states have separate versions of their tax returns for nonresidents or part-year residents - that is, people who earn taxable income in that state live in a different state, or who live in the state for only a portion of the year. These nonresident returns allow taxpayers to specify which which income is subject to the state's taxes, and which is not.
About the Individual Income Tax
The IRS and most states collect a personal income tax, which is paid throughout the year via tax withholding or estimated income tax payments.
Most taxpayers are required to file a yearly income tax return in April to both the Internal Revenue Service and their state's revenue department, which will result in either a tax refund of excess withheld income or a tax payment if the withholding does not cover the taxpayer's entire liability. Every taxpayer's situation is different - please consult a CPA or licensed tax preparer to ensure that you are filing the correct tax forms!
